In a closed aquarium, toxic compounds can build up very quickly, in fact fish never stop producing waste throughout the day, so continuous filtration is necessary to ensure their survival.

Not only does it remove harmful elements from the tank, it also retains waste, oxygenates the water and provides an ideal surface for the growth of nitrifying bacteria.

A combination of mechanical, biological and chemical filter media is necessary to help you achieve optimal water conditions.

Mechanical filtration.

Removes waste and particles through mechanical filters.

Mechanical filtration is a type of filtration which does not alter the chemistry of the water.

Its objective is to retain and eliminate waste and debris, that is, to eliminate fish excrement, sediment, undigested food, dust, etc.

Mechanical filtration will not only contribute to the overall appearance of your aquarium, but is also important in improving the effectiveness of the biological filtration of the filter.

While the foam or mechanical pad will filter out solids as the water passes through them, it will also prevent these solids from reaching the biological media and creating dead zones (places where bacteria can accumulate).

Denitrifying bacteria, which are highly desirable, will prefer higher oxygen levels and a clean surface to establish colonies.

Many species of bacteria that are not desirable, on the other hand, will prefer surface areas with low oxygen levels and high organic content.
